- Origin of the data is ASR .
- Format of the data is generated by a Klippel NFS .
- Sensitivity: 83.2dB (avg. 100Hz-1kHz for 2.83V measured at 1m)
- -3dB (resp. -6db) point v.s. reference is at 95.2Hz (resp. 74.7Hz).
- Reference level is normalised to -0.2dB computed over the frequency range [300.0Hz, 5000.0Hz].
